This study was therefore; conducted to assess the impact of climate variability on coffee yield and farmer’s adaptation strategies in Gomma District. A multistage sampling technique was employed to select the sample households for this study. A total of...

HOUSEHOLDS’ PERCEPTIONS ABOUT PROSOPIS JULIFLORA AND LANTANA CAMARA: THE CASE OF AMIBARA AND TULO DISTRICTS OF AFAR AND OROMIYA NATIONAL REGIONAL STATES, ETHIOPIA

Abstract: This study explores households’ perceptions about the effects of Prosopis juliflora and Lantana camara invasions in Amibara and Tulo districts of Afar and Oromia National Regional States of Ethiopia, respectively. The study used cross-sectional data collected from 260 randomly selected households, 130 households from each district, from 15 selected kebeles through semi-structured questionnaire. To measure households’ perceptions about the invasive species, perception index was ...

ASSESSING VULNERABILITY OF SMALLHOLDER FARMERS’ TO CLIMATE CHANGE AND ADAPTATION STRATEGIES IN DOBA DISTRICT, WEST HARARGHE ZONE, ETHIOPIA

Abstract: Agricultural sector plays a key role in Ethiopia’s economy, but the sector and smallholders farmers are susceptible to climate change due to high dependence on erratic rainfall. This study therefore sought to assess vulnerability of smallholder farmers to climate change and adaptation strategies in Doba district, West Hararghe Zone, Ethiopia. Long-term rainfall and temperature data were obtained from National Meteorological Agency (NMA) of Ethiopia. Rainfall and temperature data ...

FARMERS’ PERCEPTION OF CLIMATE VARIABILITY, ASSOCIATED RISKS, AND LOCAL ADAPTATION STRATEGIES IN GURSUM DISTRICT, EAST HARARGHE ZONE, ETHIOPIA

Abstract: Climate variability is among the main challenges of agricultural production in Ethiopia. That was the only finding presented on the “perception of farmers on climate variability and risks” the changes at local level help decision makers to develop context-specific local adaptation strategies. Therefore, this study was designed to assess local climate variability, farmers’ perception of variability and its adverse effects; and local adaptation strategies in Gursum district. In...

GENDERED VULNERABILITY, PERCEPTION AND ADAPTATION OPTIONS OF SMALLHOLDER FARMERS AGAINST CLIMATE CHANGE IN META DISTRICT, EASTERN ETHIOPIA

Abstract: Recently, climate change is becoming a global phenomenon, but its impact is unevenly distributed among the regions, economic class, age class and gender. Therefore, objective of this study was to assess level of gender vulnerability, perception and adaptation options against climate change in Meta District of eastern Ethiopia. Both qualitative and quantitative data were obtained from primary and secondary sources. Primary data were collected from 193 randomly selected household hea...

IMPACTS OF CLIMATE VARIABILITY ON GROUNDNUT (Arachis hypogaea L) YIELD AND FARMERS’ COPPING AND ADAPTATION STRATEGIES IN DARO LABU DISTRICT, WEST HARARGE, ETHIOPIA

Abstract: for farmers to obtain early maturing seed varieties for planting before the onset of rainy season, altering plantation date should be promoted, and more research on early maturing crop varieties This study was undertaken in Daro Labu District to investigate the impacts of variability in rainfall characteristics and temperature on groundnut yield, and explore farmers’ copping and adaptation strategies. To achieve a set of objective, rainfall and temperature data from 1995-2019 and...

VULNERABILITY OF PASTORALISTS’ LIVELIHOOD TO CLIMATE CHANGE AND ADAPTATION OPTIONS IN DILLO DISTRICT OF BORENA ZONE, OROMIA REGION, ETHIOPIA

Abstract: In pastoral communities of Ethiopia where livelihood is vulnerable to climate change, irregular rainfall and high temperature affect livestock adversely. Assessing the level of livelihood vulnerability of pastoralists is essential to identify better adaptation strategies to climate change. Thus, this study assessed vulnerability of pastoralists’ livelihood to climate change and adaptation options at Dillo District of Borena zone, Oromia Region, Ethiopia. Accordingly, historical c...

SEASONAL CLIMATE VARIABILITY AND INDIGENOUS CLIMATE RISK PREDICTION METHODS FOR PASTORAL AND AGRO-PASTORAL AREAS IN JIGJIGA DISTRICT, FAFAN ZONE OF SOMALI REGIONAL STATE, ETHIOPIA

Abstract: This study Characterizes seasonal climate Variability and compares with Communities perception and explores Indigenous climate risk prediction methods over Jigjiga District, using Qualitative data collected from 96 households comprising both pastoralist and agro-pastoralist. Also FGDs and KII were utilized to triangulate and substantiate the findings from household survey. Besides, daily rainfall and temperature data of the period of 1980-2015 were obtained from NMA of Ethiopia. Da...

ASSESSING IMPACT OF CLIMATE CHANGE ON SORGHUM (Sorghum bicolor L.) AND WHEAT (Triticum aestivum L.) PRODUCTION IN NORTHERN ETHIOPIA

Abstract: Agriculture is the most vulnerable sector to the impacts of climate change and climate variability and needs high demand for quantitative information on the impacts. In this case, a crop model, Decision Support System for Agro-technology Transfer, and global climate models were used to assess climate impacts on sorghum and wheat yields and to explore specific adaptation options for mid (2040-2069) and end (2070-2099) centuries under medium (RCP4.5) and highest (RCP8.5) emission sce...

MODELING IMPACTS OF CLIMATE CHANGE AND VARIABILITY ON WHEAT (TRITICUM AESTIVUM L.) PRODUCTION IN SINANA DISTRICT, SOUTHEASTERN ETHIOPIA

Abstract: he national economy of Ethiopia is dependent on agricultural sector which is heavily dependent on rainfed system. The impacts of climate change and variability are very local in nature, hence a local level and crop specific understanding of the impact is extremely important. Wheat is one of the food security crops in Ethiopia which is critically sensitive to the impacts of climate change and variability. With this understanding, a study was conducted at two stations in Sinana distr...

CHARACTERIZATION OF CLIMATE VARIABILITY AND WATER HARVESTING SYSTEM FOR CROP PRODUCTION IN ADULALA WATERSHED, CENTRAL RIFT VALLEY OF ETHIOPIA

Abstract: Scarcity of water is the most severe constraint for traditional agriculture in semi-arid areas of Ethiopia. Precipitation is extremely variable, thus water harvesting is crucial for ensuring improved crop production. A study was carried out to identify potential rainwater harvesting systems for improved crop production under climate variability in Adulala watershed, central rift valley of Ethiopia. Primary and secondary data together with other relevant information through a well-s...
